Detailed Description

The CosFirstToLastAngleFeature class calculates the cosine of the angle between the first and last point.

From: Rubine, D. Specifying Gestures by Example. Computer Graphics 25, 4 (July 1991), 329-337. Page 333:

f6 = cos b = (xlast - xfirst) / f5
   = (xlast - xfirst)
     / sqrt( (xlast - x0)^2 + (ylast - y0)^2 )
